Cook the pasta following the instructions on the package.
Pour the olive oil into a pan to stir-fry onion, garlic, and spinach. Then add the tuna (previously shredded) and cook for 3 minutes.
Next, add in the cherry tomatoes, milk cream, wine, and stir for a couple of minutes. If you want the sauce to be lighter, add some water while cooking.
Season with salt and pepper, add the pasta and mix it all well.
